Flimsy the donkey shirt logo

I’m looking for a logo for a shirt featuring a donkey named Flimsy. I want a Cartoon/Illustrative logo with a Bright colour palette, plus an illustrated mascot of Flimsy the donkey. I'll need to have the rights to be able to use the logo on my website and on merchandise. I do not need a slogan included - just the logo. Please provide mockup samples and revisions so I can be sure I am getting what I want.
